Show me where Jesus condemned the polygamy practiced by the prophets.
Matt 19: 3-9 And the Pharisees came near to him, tempting him, and saying to him, 'Is it lawful for a man to put away his wife for every cause?'
And he answering said to them, 'Did ye not read, that He who made [them], from the beginning a male and a female made them, and said, For this cause shall a man leave father and mother, and cleave to his wife, and they shall be -- the two -- for one flesh so that they are no more two, but one flesh; what therefore God did join together, let no man put asunder.'
They say to him, 'Why then did Moses command to give a roll of divorce, and to put her away?'
He saith to them -- 'Moses for your stiffness of heart did suffer you to put away your wives, but from the beginning it hath not been so. ‘And I say to you, that, whoever may put away his wife, if not for whoredom, and may marry another, doth commit adultery; and he who did marry her that hath been put away, doth commit adultery.'
Okay, foolish lawyer, parse the teaching of Jesus! But know this, on several threads recently the teaching of Jesus has been given, this same passage, and the teaching condemns taking another wife unless the original wife has committed whoredom or is dead. PERIOD. Additionally, since Christians believe Jesus IS GOD and IS THE ULTIMATE AUTHOR OF THE BIBLE, all the teachings found in the letters of Paul regarding leaders of the Church apply to marriage.
You might think yourself quite adept, to try and find exceptions to the Bible teachings, but you are ultimately playing Satan’s game in doubting God and seeking ways to parse Him as unfaithful to His teachings or double-minded. Take care you do not lose your immortal soul while winning a foolish parsing contest.
